Question

Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. What is the difference between active transport and passive transport?

Answer 1

passive transport does not require energy while active transport requires energy.
passive transport moves molecules with concentration gradient(from high to low concentration)but active transport moves molecules against concentration gradient

Answer 2

Active Transport requires the cell to expeend energy, while passive does not

Step-by-step explanation:

Active transport is the movement of materials from areas of lower concentration to areas of higher concentration. This requires a cell to expend energy. Active transport includes endocytosis, exocytosis, and cell membrane pumps.

Both of these processes are important in the movement of materials in and out of cells.
